High precision machining apparatus used for electronic equipment outer shell

Abstract

The invention discloses a high precision machining apparatus used for an electronic equipment outer shell. The high precision machining apparatus used for the electronic equipment outer shell comprises a feeding supporting seat, a polishing supporting seat, a plurality of mechanical arms, a polishing head and a material conveying clamping fixture, the polishing head and the material conveying clamping fixture are correspondingly connected with the tail end nodes of the mechanical arms in an installing mode, the feeding supporting seat and the polishing supporting seat are arranged in the circumferential direction of the mechanical arms, the feeding supporting seat comprises a supporting frame and a feeding table installed on the supporting frame, the tail-end nodes of the mechanical arms are connected with an installing seat, the polishing head and the material conveying clamping fixture are installed on the installing seat, an air outlet communicates with a second cavity body, the lower end of a core body is connected with a rotating shell, the central axes of the installing seat, a bearing and a rotating head coincide, and the central axis of the rotating head does not coincide with the central axis of the core body. According to the high precision machining apparatus used for the electronic equipment outer shell, vacuum adsorption of a workpiece is realized through an adsorption hole and an adsorption line groove, the accurate position and stability of the workpiece are ensured in the polishing process, the situations of offset and the like in the polishing process are avoided, and the polishing accuracy and stability are ensured.

Description

technical field [0001] The invention relates to a high-precision processing device used for electronic equipment shells, and belongs to the technical field of processing precision parts of electronic products. Background technique [0002] At present, most of the appearance structural parts / accessories of mobile phones and laptops on the market are made of metal materials. The forming of metal materials mainly includes aluminum extrusion, die-casting, forging and other methods. No matter which forming method is used, CNC machining centers are required for processing after forming. Due to the existence of poor appearance such as knife marks and scratches in the CNC machining process, a series of appearance retreatments such as passivation, grinding and polishing, spraying, and anodic oxidation must be carried out on the workpiece. However, on each workpiece, the area that needs to be polished is often only in a local area, because the grinding device cannot identify the local...

Problems solved by technology

However, on each workpiece, the area that needs to be polished is often only in a local area, because the grinding device cannot identify the local area that needs to be polished, and the local grinding can only be achieved through comprehensive grinding, which is time-consuming and labor-intensive, and the processing efficiency is low.
